curaga:
The error message is pretty clear, you have a wrong password/username. Alternatively your mail server may require some other authentication type.

FWIW, there is a #claws IRC support channel on freenode.net.

Curaga - Thanks for your reply.Since I can receive mail,my login and passwordshould be correct, right?I think your 2nd suggestion is correct.The probable issue is my smtp server requiressome other authentication thingy.AT&T seems to be a bit more complicatedthan any other ISP I used over the past15+ years in 3 countries.

TinyPoodle - Thanks for your info.Didn't find a forum, but I didsubscribed to the Claws Mail mailing list.Hopefully someone there knowshow to setup Claws w/ an att.net account.

Thanks friends
